    Would not the 4500k produce the most usable light? I know the 5700K is heading closer to a blue hue. What is your take on this?

    i've read that 5 to 6K is the brightest white.

    Color temp has nothing to do with brightness.

    5600 is the (average) color of daylight, so a bulb with 5600K will illuminate things the same way daylight does. Whether or not you like that is of ocurse personal preference.

    If you go above 6000 Kelvin, you will get blue to even purple color.
    Go below 5k, and the color becomes more yellow/orange ('warmer' in our perspective).

    But the same bulb with different color temp will basically give the same brightness (as in amount of light projected). Note also that perceived brightness is very much influenced by contrast (the difference in light relfection between different objects/colors). And contract is largely influenced by color temp of the light that is being reflected.

    ok it's the whitest light and thus perceived as the brightest output?
    what ever wording you choose to use, everyone says choose between 5-6K for the most light down the road.

    squadraquota hit it on the head. I was one of the first vendors pushing lower K #s to off road racers some 12 years ago, mostly for helmet light usage. Once we where copied, other companies started pushing 6500K helmet mounted lights attempting to show how they looked brighter to look into.:huh
    who cares how bright a light is to look into, its what's on the business side that counts.
    For off road the lower K the better.



    A lower K will decrease shadows and in general allow you to see better in an off road setting. For Road usage, I don't really think it matters much Not to many rocks, roots or jumps to deal with. Its best to stay away from lights over 6200K

    What happened to 4300 k being the closest to daylight ?
    That was always the standard when choosing Hid.

    I don't know where you got that info. It completely contradicts what I know to be true.

    It may be wrong ,but it seems that was the choice in the HID lighting for long distance night riding.
    If I remember correctly most of the high end lighting was 4300k.
    I think Bruno of Future Vision also recommended this.
    Here is an example if the link works.

    I disagree.
    I could throw back links etc all day long. So what.. potato's pototo's
    Im working hard to have different color options for all riders.
    I don't know Bruno or future vision.
    I do know what works . With nearly 20 24 hr off road race finishes and several wins, as well as 12 years offering quality lighting products to racers, Ill go by my own experience.
    To each there own.

    I'm not questioning your expertise.
    You have alot of lighting experience,I just make my lighting choices by recommendations.
    I'm just simply mentioning some things I have seen riders doing.

    The efficiency of incandescents drops of as temp goes up. So, for the same watts in at 4300k you got more photons that at 6000k.

    What the story is for LED's, no idea. White LED's push out UV and get it converted to 'white' with phosphors. It's not necessarily the same as for HID's though. I'd suspect it depends on what the most efficient phosphor mix is.

    I know you're at the testing stage now; but I'm wondering if you have an idea of about how far down the road until these are available for sale and about how much they will go for.

    The bulb reliability is looking great, we have realized a few issues with fit on certain bikes. one issue is getting to the retainers after the bulb is installed in the housing AKA gs800
    Not sure what we can do about that right now.
